I think there are some points we can learn from this article.
From the Wall Street Journal:
You don’t need a car to get road rage.
For many people, few things are more infuriating than slow walkers—those seemingly inconsiderate people who clog up sidewalks, grocery aisles and airport hallways while others fume behind them.
Researchers say the concept of “sidewalk rage” is real. One scientist has even developed a Pedestrian Aggressiveness Syndrome Scale to map out how people express their fury. At its most extreme, sidewalk rage can signal a psychiatric condition known as “intermittent explosive disorder,” researchers say. On Facebook, there’s a group called “I Secretly Want to Punch Slow Walking People in the Back of the Head” that boasts nearly 15,000 members.
. . .
Signs of a sidewalk rager include muttering or bumping into others; uncaringly hogging a walking lane; and acting in a hostile manner by staring, giving a “mean face” or approaching others too closely, says Leon James, a psychology professor at the University of Hawaii who studies pedestrian and driver aggression.
. . .
How one interprets the situation is key, researchers say. Ragers tend to have a strong sense of how other people should behave. Their code: Slower people keep to the right. Step aside to take a picture. And the left side of an escalator should be, of course, kept free for anyone wanting to walk up.
“A lot of us have ‘shoulds’ in our head,” says Dr. Deffenbacher. Ragers tend to think people should do things their way, and get angry because the slow walkers are breaking the rules of civility. It’s unclear exactly why some people harbor such beliefs, Dr. Deffenbacher says. Such ways of thinking are generally learned from family, friends or the media, he adds.
Ragers’ thoughts tend to be overly negative, over-generalized and blown out of proportion, leaving them fuming about how they can’t stand the situation, how late they are going to be, and how this always comes up, Dr. Deffenbacher says. In contrast, someone blissfully free of sidewalk rage may still be frustrated, but thinks more accepting thoughts such as, “this is the way life is sometimes” or, “I wish that slow person wasn’t in front of me,” he says.
